Source: adapted from EPA420-R-97-007.Lowry-Type Transportation / Land Use ModelThe Lowry model links two spatial interaction components represented
as the location of industrial (basic sector) employees and the location
of service (non-basic sector) employees. Both are impeded by the friction
of distance, referring to transport costs. The core of the model is
exogenous, derived from a regional economic model, where the location
of basic (industrial) employment is inputted.
